Endolymphatic sac tumours (ELST) are rare tumours of the petrous temporal bone. They may arise sporadically or be associated with von Hippel-Lindau disease. Their differential diagnosis is discussed. We present the clinical and histopathological features of two new patients with ELST and outline the management of their condition. In addition, we review

Ischemia of the Endolymphatic Sac
Acta Oto-Laryngologica, 1992A decrease in vascular density in the endolymphatic sac was suspected as a factor in the pathogenesis of endolymphatic hydrops in Meniere's disease. The present study was undertaken to explore this possibility by cutting the posterior meningeal artery and the sigmoid sinus above and below the external aperture of the vestibular aqueduct or by incision ...

Histopathology, 1998
This review article surveys clinical and pathological literature on endolymphatic sac tumours (ELST) and summarizes characteristics that describe the entity.ELST are rare neuroectodermal neoplasms in the petrous bone, originating from inner ear structures. They can be encountered sporadically or in von Hippel–Lindau disease.

Neurosurgery, 1995
The endolymphatic sac is part of the membranous labyrinth; it plays an important role in the hearing mechanism. Injury to the endolymphatic sac may, over time, severely compromise hearing. The endolymphatic sac is located in a duplication of the dura of the posterior aspect of the petrous pyramid and is, therefore, in the surgical field of many ...

Otolaryngologic Clinics of North America, 1994
Endolymphatic sac enhancement surgery has proved, over the last several decades, to be a conservative and relatively safe procedure for patients in whom extensive empirical medical therapy has failed. The operation can usually be done as an outpatient procedure or with a one-night postoperative stay, and it has relatively low morbidity.

Otolaryngologic Clinics of North America, 2015
Endolymphatic sac tumors (ELST) are slow-growing, locally aggressive, low-grade malignancies that originate from the epithelium of the endolymphatic duct and sac. ELST often present with sensorineural hearing loss, tinnitus, and vertigo, which may mimic Meniere disease. Large tumors may present with additional cranial neuropathies.

The Journal of Laryngology & Otology, 2003
We present a case of a papillary tumour of the petrous bone. The established terminology for this rare neoplasm is endolymphatic sac tumour (ELST) but the true origin remains controversial. ELSTs are associated with von Hippel-Lindau disease. They are locally invasive, highly vascular and often require endovascular embolization prior to surgery.
